ing out the stumps, .or for boring apertures in logs, timber, and thelike.

The invention consists of certain features of construction andcombinationsof parts which will be hereinafter fully described andpointed out in the Claim.

In the accompanying drawings-Figure 1 is a view in erspective; Fig. 2 isa view in side elevation; and Fig. 3 is a sectional view.

A, represents the base, and 1 1 are the standards connected to the base.'Vertical slots 2 are formed in the uprights or standards, and connectedto the standards 'are segment plates 3, by bolts 4 and 5. The segmentplates are .provided with curved slots 6 through which the bolts 5 pass.Grooves or guideways 7 are formed in the plates through which the frame8 is adapted to slide. Journalcd in the frame is the auger 9, which isprovided with a gear 10 on the end which meshes with a pinion 11 mountedon the crank shaft 12. I-Iandles 13 are connected with the shaft 12 forrotating the pinion 11 for transmitting rotary motion to theauger 9. Abreast plate 14 is connected' to the frame S, which is placed against.the breast of the operator in the boring operation for forcing theframe through the guides 7 in the plates 3 as the auger is passingthrough the Object bored. After the hole has been bored in the Object,by pulling upon the breast plate 14 the frame will be drawn through thegrooves or guides 7 in the plates 3, thereby drawing the auger from theobject. By raising or lowering the breast V Specfiation of IettersPatent. Patented Application filed April 29, 1909. Serial No. 492,903.

plate the frame is moved through the plates 3 to obtain the differentangular adjustments. This is' accomplished by the curved y slots 6'whichare formed in the plates 3 so thafithe different adjustnients can'beobtained by nerelyi moving the frame at an angle for obtaning theangular adjustment desired -'By loosenngthe bolts 4 and 5 the plates 3and frame 8 `can be elevated or adjusted vertically to obtain differentelevations of the slots 2, thusproviding means `whereby the auger or bitcan be adjusted for boriig at different angles.

From the foregoing it will be seen that I have provided a machine whichis simple in construction and by which I am enabled to obtain'difl'erent angular' adjustments by simply moving the frame, and theframe can be adjusted vertically at difierent elevations.

Itis evident that more or less slight changes might be made in the formand arrangement of the several parts described without departing fromthe spirit andscope' of my nvention, and hence I do not wish to belimited to the exact constructionherein set 'forth, but

I Claim'. as new and desire 'to secure by Letters Patent .is v g 'In 'aboring machine, the combination with a* base having vertically slottedstandards, segment plates 'having curved islots, each standard havingtwo bolts in the slot thereof, said bolts'extending through the slotofeach'st andard into said segment plates, one to forna pivot and theother throughthe slot to secure the plates in axial adjustment, ofaframe slidably connected with the segment plates, an auger carried bythe frame, a breast-plate for applying pressure to the frame to feed orslide the auger forward, and means for turning the auger.

In testimony whereof* I affix my signature', in the presence of twowitnesses.
